The William H. Zimmer Power Station, located near Moscow, Ohio, is a coal-fired power plant. It was originally intended to be a boiling water reactor type of nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. Today, the plant generates 1400 gross MWe and 1300 net MWe. Zimmer Power Station is the largest single-unit power facility in the United States and is majority-owned by Duke Energy. During the construction of the plant, the Little Indian Creek was routed through the plant to protect fish populations. The plant now has several unique Environmental Protection features to keep the creek at its natural state.
